CHAPTEE III. 

JAMES W. QUEEN & CO. AKE SOLE AGENTS BY APPOINTMENT IN 

PHILADELPHIA, AND PKINCIPAL AGENTS IN THE 

UNITED STATES, FOE THE 

CELEBRATED SWISS DRAWING INSTRUMENTS. 

Although there are several makers of drawing instruments in Switzerland, yet 
there is but one manufacturer whose instruments uniformly come up to a standard ol 
absolute perfection in quality of material and excellence of finish. The divider joints 
work regularly and smoothly, the points are carefully tempered and rounded, the 
pens dressed to draw a smooth line of any thickness in whatever position held. 

Other Swiss manufacturers imitate the form of these instruments^ but cannot 
imitate their perfection in finish.

AMES' PATENT UNIVERSAL SQUARE. 



This square combines, in a most convenient fonn, 

five different instruments, viz., The Try-square, the 
Miter, the T-square, the Graduated Kule, and 
(what is entirely new) the Centre-square, for find- 
ing the centre of a circle. 

Fig. 1 explains . its application as a Centre- 
square. Put the instrument over the circle, asthe 
end of the bolt or shaft, with the arms b a, a e rest- 
ing against the circumference, in which position 
one edge of the rule, a d, will cross the centre. 
Mark a straight line in this position ; apply the in- 
strument again to another part of the circumfer- 
ence, and mark another line crossing the first. The 
point where the two lines cross each other will be 
the centre of the circle. The whole ia the work 
of a moment. Fig. 2 explains the application of 
the instrument a3 a carpenter's Try-square, n, and

These instruments can be furnished with millimeters (in the place of sixty-fourths of an inch), 
and provided with a yernier to read to one-fiftieth of a millimeter. 

The cut is a fac-simile of one side of our hardened cast-steel Improved Vernier 
Caliper, a light, convenient, and valuable instrument for machinists' and tool- 
makers' use in obtaining correct measurements. The side represented above is grad- 
uated upon the bar to inches and fiftieths of an inch, and by the aid of a vernier is 
read to one-thousandths of an inch. The opposite side is graduated to inches and 
sixtv-fourths of an inch. The outside of the jaws are of suitable form for taking 
inside measurements, and when the jaws are closed measure 250 one-thousandths of 
an inch in diameter. This Caliper will measure one inch and eleven-sixteenths, 
outside diameter, when the jaws are opened full size.

The Drawing Board above illustrated is the best, and deserves recommendation, as 
it is the only one which possesses the qualities a good and true board should have. 
It is made of pinewood, glued up to the required width, with the heart side of each 
piece of wood to the surface. A pair of hardwood battens are screwed to the back 
the screws pass through the ledges in oblong slots, bushed with brass, which fits 
closely under the heads, and yet allows the screws to move freely when drawn by 
the contraction of the board. To give the battens power to resist the tendency of the 
surface to warp, a series of grooves are sunk in half the thickness of the board over 
the entire back. These grooves take the transverse strength out of the wood to allow 
it to be controlled by the battens, leaving at the same time the longitudinal strength 
of the wood nearly unimpaired. 

To make the two working edges perfectly smooth, allowing an easy movement with 
the square, a slip of hardwood is let into the end of the board. The slip is afterward 
sawn apart at about every inch to admit contraction.

This invention consists in tlie application of curved and straight Slot Links, 
Thumb-screws, and an additional Bearing-bar to trestles of the ordinary form, by 
which means adjustment to the height of the Draughtsman is obtained, sitting or 
standing, from the height of a table to the full height of a drawing board, from the 
horizontal to any required angle of inclination on either side. 

Figures 1 and 2 show side and end elevations of Trestle, suitable for the Artist, 
Engineer, or Architect's office. 

Figure 3 shows the side elevation of a Double Trestle for the use of Mechanics,

THE "UNIVERSAL" RULER AND SECTION LINER. 



,--^" , 




This Euler combines the following advantages : It is accurate, neat, simple, 
AN'D durable, being made of steel and brass nickel-plated. The cuts below were 
drawn with this Euler, and illustrate a few of the many things which may be done 
with it. Lines may be drawn in any direction and at any distance apart, "from j^ 
of an inch to any distance desired. 

To draw_ parallel lixes, turn the shaft toward you by the rubber sleeve, and 
draw the line along the edge of the pivoted arm, being careful to rotate the shaft in the 
opposite direction after hearing a click, until it stops. If a smaller space is required 
set the pivoted arm at an angle, by means of thumb-nut and slotted-quadrant, draw- 
ing the lines along the edge of the arm as before. Larger spaces may be obtained 
by allowing the instrument to give more than one click. 





r 



For curved or irregular avork, attach the desired curve to Euler bv two 
thumb-nuts in the centre and proceed as before, using the curve for a ruling edge. 

To draw parallel ciRCLES.use the soft centre point on the right hand end of 
pivoted arm, and draw circles with ordinary circular pen. 

To shade cylinders,^ place the pivoted arm so as to space a very short distance, and 
draw lines at the required distance apart.

This Instrument is for indicating 
sections of objects in mechani- 
cal and architectural draw- 
ings, for drawing screw 
threads, laying out the spaces 
for brick work, lottorings on 
drawings, and all cnscs where 
narrow s})acetl parallel lines 
are needed. AVith it a person 
of moderate ability or jiractice 
can produce an eli'ect of nni- 
fornn'ty aud neatness, in sec- 
tional drawings, almost, or 
(piite eipial to the engim^ di- 
vidiiiL;- of engravings. Th^ 



80 G. S. WOOLMAX, :SBW YORK. 

instrument consists of a ruler, covered on the under side with India-rubber cloth, a 
triangle with a clamping-screw, passing through near one of its edges, and a plate, 
with the necessary arrangement for producing a movement over equal spaces. The 
several parts are placed together as represented in the engraving, there being a little 
spring beneath the front edge of the top plate, which presses against one edge of the 
ruler, while the triangle is clamped against the other edge. The ruler may be 
placed upon the paper in any desired position, the India-rubber cloth underneath 
keeping it there with perfect security, and it thus acts as a guide for the triangle, 
which can be moved along over equal steps by alternately pressing down the ivory 
button and letting it spring back. Tliis movement is produced by the action of a 
little pawl upon the ruler, wliich is always to be kept pretty sharp, so that it will take 
a quick and certain hold. The length of the steps taken, or the distance between 
the lines drawn, is regulated by the screw above the spring, the distance moved over 
each time being greater as the spring is allowed to have more play. By changing 
the clamping-screw on the triangle, any edge can be placed against the ruler.

PROFILE PAPERS. 

Printed in red or green. 

After a long series of experiments, we are now prepared to furnish in sheets, and 
in continuous rolls, a perfect article of Profile Paper. Our plates, A and B, are so 
well known amongst engineers, and have met with such universal approval, that a 
detailed description of the rulings seems unnecessary. 

We have recently added another plate with metric divisions, wliich, we trust, will 
meet the wants of the engineering profession desiring to use this scale.

Blue Prints, made to orJer from tracings, cost, according to size of tracing, at 10 
cents per square foot. 

White Prints (blue lines on white back-groimd), so that colors can be added to 
prmts made to order, according to size of tracing, 12 cents per square foot For 
this purpose draughtsmen should be careful that lines of tracin^^ are clean and 
black. Higgms' American Drawing Ink, '' General," is the best ink for this purpose.

THE BLUE PROCESS OF COPYING TRACINGS. 



Special attention has recently been directed to this easy process of copying trac" 
ings, and its great value to all Engineers, Architects, and Mechanical Draughtsmen 
fully recognized. 

The instructions in using are — 

1. Provide a flat board as large as the tracing which is to be copied. 

2.^ Lay on this board two or three thicknesses of common blanket or its equivalent, 
to give a slightly yielding backing for the paper. 

3. Lay on tlie blanket the prepared paper with the sensitive side uppermost. 

4. Lay on this paper the tracing, smoothing it out as perfectly as possible, so as to 
insure a perfect contact with the paper. 

5. Lay on the tracing a plate of clear glass, which should be heavy enough to press 
the tracing close down upon the paper. Ordinary plate-glass of three-eighths thick- 
ness is quite sufficient. 

6. Expose the whole to a clear sunlight by pushing it out on a shelf from a win^ 
dow, or in any other convenient way, from four to six minutes [in winter, six to ten 
minutes]. If a clear sky only can be had, the exposure must be continued from 
twenty to thirty minutes, and under a cloudy sky from sixty to ninety minutes 
may be needed, the shade depending on the time. 

7. Kemove the prepared paper and wash it freely for one or two minutes in clear 
water, and hang it by one corner to dry.

WILLIAMS' INK SAUCER. 




Various forms and sizes of China Nests and Slabs have long been in use for grind- 
ing or mixing India Ink and Water Colors, but none now in the market combine so 
many desirable qualities as the Cup shown in above cut. It consists of a saucer 3^ 
inches in diameter, made of specially prepared milk-white glass, with cover; both 
are made with great care to prevent chipping Or breakage, which avoids the objec- 
tion to those having covers now in use. All edges of the cover and saucer which 
touch are ground, thus making it air-tight, and by preventing evaporation, preserves 
the ink as long as may be desired. The grinding surface is made either smooth or 
roughened, and is sunk sufficiently far below the lip as to prevent the annoyance of 
the ink splashing on the outside whilst being mixed. In the centre is a deep well, 
adapted to receive and contain the ground ink. 

In short, we feel confident that when once introduced amongst draughtsmen it w»U 
meet with the large sale that its cheapness and excellence deserves. 

Price, either with smooth or roughened grinding surface, only 50 cents.

QUEEN & CO.'S STANDARD TECHNICAL WATER COLORS. 

After many experiments, "we have at last perfected a series of technical colors that 
■we believe will meet a want long felt among draughtsmen for a ready-mixed 
standard color of fine grade, suitable for all branches of mechanical drawing. 

The advantages we claim for these colors are : 

1. All time usually spent in mixing the colors to proper shade is saved, and uni- 
formity in tint is invariably produced. 

2. The colors have been very carefully prepared, and are standard, such being 
universally used in all branches of mechanical drawing both in Europe and the 
United States. 

3. Tliey are made of the finest quality of writer colors, and being put in moist form 
in pans, are always ready for use, and the liability to crumble of the cake colors is 
avoided. 

The set described below contains the colors generally used by Architects, Machin- 
ists, Civil and Mechanical Engineers.

The Lea^ding Liquid Drawing Ink. 




^^^^^^^^'^^^^^"^^"^^^^ :gI^dsirTr^\ 



This Ink, first introduced in 1880 
under the name of the " American 
Drawing Ink," or the " American 
India Ink," has now gone into general 
use, and is recognized as the leading 
drawing ink in the United States, 
having extensively displaced the origi- 
nal stick ink, and superseded all the 
crude liquid inks previously attempted. 
It is not a solid ink ground up, but A 
NEW NATIVE INK, made fluid from the 
outset; and it will never become gelat- 
inous, thick or offensive, or deposit 
carbon, like all so-called" Liquid Inks" 
with which Draughtsmen have been 
heretofore afflicted. It thus fills the 
long felt want of Draughtsmen. 



Sectioa of Bottle with Imprcvel Combined 
Stopper and Fen Filler. 

A PERFECT LIQUID INK. 

j&i^^wAirs mm&m^. &j^yf^jSkis® giociip. 

This Ink is put up in a special bottle (see cut), with a quill for filling the 
pen and an improved stopper, and is thus ready for instant use. 

Beware of dealing in any inks not made by us, using the label title " Water- 
proof Drawing Ink," as such is an infringement on our label copyright No. 3693,

COPYRIGHT 1888, BY IM. LORINI. 



This useful diagram is rapidly growing in favor among engineers and 
surveyors. The calculation of latitudes and departures, even with the best 
books published, is a very tedious process, and few men can be certain of 
the accuracy of their work in the case of a long traverse. It is therefore 
necessary that the calculations should be checked. The labor involved in 
the operation of checking is as great as that of making the original calcu- 
lations. Also of value in Bridge Building. 

'With the Graphic Traverse Table, the checking becomes very easy. 
Two persons working together can check from 175 to 200 courses in one 
hour. The results obtained agree very closely with the calculations ; so 
closely, that in many instances the table can be used alone, and the calcu- 
lations dispensed with, the average error not exceeding .001 per foot. It 
is not difficult to use, and any person can become expert with it after 
a few minutes' practice. 

Full directions sent with each table. Printed on linen-backed paper. 
Size of diagram, 15x15 inches.

The Surveyor's Transit, as above illustrated, has a Telescope, from ten to twe -^ 
inches long, constructed with the finest lenses ; under the telescope a level is attached 
for taking such levels as may occur in the practice of a surveyor. On one end of the 
axis of the telescope a divided circle, 42- inches diameter, is attached for reading to 
minutes angles of elevation and depression. The rim of the compass box is divided 
to I degrees, and is provided with a nonius for adding and subtracting the magnetic 
variations of the needle. The limb on the divided circle outside the compass box, ia 
provided with two verniers at right angles to the telescope and read to minutes. 
The tripod head is arranged with shifting centre, for setting the instruments quickly 
over a given point without the trouble of altering the position of the legs. The tripo<? 
l«gs are made of very strong mahogany.

The description given on page 119 for the Surveyor's Transit will apply for the 
Engineer's Transit, exceptiug that the latter has the axis or centre running from the 
lower parallel plate of the tripod head to the centre plate of the instruments, thus 
securing greater accuracy for laying of angles. The upper part of the Transit does 
not separate from the tripod head, as in the Surveying Transit, but is permanently 
iittached to the parallel plates and leveling screws, and when put in its box is 
unscrewed from the tripod at the lower parallel plate. See cut on first page of

Y Level of the most approved form and construction, with telescope 
either 16, IS, or 20 inches long. In this instrument the telescope 
is made to revolve readily and truly in tne Ys by rings of bell-metal, 
which, when desired., may be firmly clamped by the clips, and held 
in any position. It has a rack-and-pinion movement to both object 
and eye-glasses, an adjustment for centering the eye-piece and an- 
other for insuring the accurate projection of the object-glass in a 
straight line. Both of these are completely concealed fiom obser- 
vation and disturbance by a thin ring, which slides over them. The 
Ys of this level are made large and strong, of the best bell-metal, 
and each have two nuts, both being adjustable with the ordinary 
steel-pin. The level-bar is made round, of well-hammered brass, 
and shaped so as to possess the greatest strength in the parts most 
subject to sudden strains. The tripod-head has the same plates and 
leveling screws as that of the Engineer's Transit, ....

making, as we believe, the most 
efficient quick leveling arrange- 
ment yet devised. 

DIRECTIONS FOE, USE. 

Screw the instrument on the 
tripod as usual ; if not nearly 
level, unscrew the leveling head 
a very little, a bare loosening of 
the screw is sufficient. The in- 
strument will then be free to 
move upon the spherical sur- 
faces A, B, C, in any direction 
required to bring the plates ap- 
proximately level, and wiU 
held in this position by the fric- 
tion of the same surfaces. 

Now screw the head fast again, 

1. Shows the quick leveling tripod head designed firmly clamping the whole in- 
alor transit, and without shifting plate. ■, • t mi 

strument to the tripod, ihe 

final ajustment of the level is then com- 
pleted by the use of the leveling screws. 

The friction of the spherical surfaces 
may be increased or diminished at will, 
by turning the screws " D," which com- 
presses the spiral springs.

>.-* 



Architects' Compass Level, complete with tripod, 



$65.00 



This new instrument which has only been before the public for about a 
year, has already met with great favor among Architects, Builders, 
Millwrights and among Engineers and Surveyors by whom it is used 
in city work. 

The Telescope is 12 inches long and of the finest optical qualities, and is 
arranged and adjusted as in the regular engineer's level. It is 
furnished with a carefully ground, long level. The instrument turns 
upon a horizontal circle, 3-inch diameter, graduated from to 90 
each way, and is read to five minutes by a vernier which is fixed to 
the spindle. The compass has So-inch needle. 

The instrument is packed in box with strap and is furnished with adjusting 
pins, &u.

NEW TELESCOPIC SIGHT, 

JiTIA.CUABLJE TO ANY COMPASS, 



[patent applied for.] 

The New Telescopic Sight consists of a tele- 
scope furnished with the usual cross wires, etc., and 
attached to a movable band, which, as shown in the 
engraving, can be slipped over the sight of any 
compass, clamped at any point desired, and put in 
adjustment by a method so simple as tO be within 
the reach of any person Avho has a screw-driver. 

The surveyor can then use the telescope either in 
connection Avith the sights or entirely independent 
of them, running long lines, taking fore and back 
sights, and sighting up and down hills with perfect 
facility, and with an ease and accuracy surprising 
to one who has run lines only by the ordinary 
sights. 

The New Telescopic Sight can be applied to any 
compass, and those ordering it need only to give us 
the widtJi and thickness of the sight upon which it 
is to be placed to receive the apparatus, with full 
directions for its adjustment and use. It can also 
be detached when not in use, and replaced again 
without injuring its adjustments. 

No. 1. — Nine-inch Achromatic Telescope, 
of low, but sufficient power, 

No. 2. — Nine-inch Achroma- 
tic Telescope, larger diam- 
eter of object-glass and 
higher power. 
No. 3, — Same Telescope as 
No. 2, but furnished with

for measuring distances, . 20.00

below sea level to 4,000 above . . . . . 50 00 

The Surveying and Mining Aneroid has been designed and constructed 
ppecially for tlie use of Surveyors and Engineers, for the purpose of readily ascer- 
taining slight variations in gradients, levels, &c., and from its extreme sensitiveness 
will be found of considerable utility in Mining and Surveying work generally. 

Besides extreme sensitiveness, the specialty claimed for this Instrument is an 
arrangement of the Scale of Altitudes which admits of subdivision by a W'lnier, 
hitherto impracticable, owing to the Altitude Scale in ordinary use being a grniin- 
ally diminishing one, to which a Vernier cannot be applied. In the present Instru- 
ment the action has been so adjusted as to give accurate readings upon a regular 
Scale of Altitudes, the Barometrical Scale of Inches liaving been made progressive 
80 as to afford the correct relative readings with the Scale of Altitudes. 

For Mining purjmscs the entire circle of the dial is graduated to rejixesent 6 
inches of the mercurial column, i.e., from 27 inches to 33. Tbis scale will register 
about 2000 feet below sea-level to 4000 feet above; tiio finest divisi<»n8, hundrtdlbs of 
the Altitude Scale, represent 10 feet measurements, which can be again subdivided by 
the Vernier Scale to shif/lefeet. The Vernier Scale is moved bv a rack-\v»trk a*ljust- 
ment, and a magnifying lens which rotati's on the outer circunifcrciue i>f tlic Instru- 
ment facilitates the reading of minute (juantitics. 

For Surface Surveying purposes, wliere it is not required to be used below sea- 
level, the InstrunuMit is made with the scale divided from 25 to 'M inclu's. thus giv- 
ing an Altitude Scale of 5000 feet above sca-lcvel only, and with tliis opvu scale imA 
the assistance of the Vernier, the same minute reading's can be easily tukeii.

The Anemometer, an instrument invented for the purpose of measuring the rate 
at which air moves in mines and ventilation passages, is now an indispensable ad- 
junct of the former, the mining laws of most States requiring that a certain number 
of cubic feet of air shall be passed to the air-ways, and the Anemometer furnish- 
ing the most convenient and satisfactory mode by which the amount of air passing 
can be determined .

1135. Hill's Kailroad Time Charts. 

The principal features of the Charts are : 

1. The positively mathematical correctness of the spacing. 

2. The ease with which the five minutes, half hour, and hour lines can be distin- 
guished, as well as their perfect clearness and cleanness. 

3. Their enormous size (28x50), admitting of larger hour-spaces than any chart at 
present in use. 

4. The excellence of the paper on which they are printed, as well as its peculiar tint, 
rendering it peculiarly fit for night work, while its cardboard-like texture obviates the 
necessity for dampening and stretching, and the consequent distortion of the diagram. 

5. Their cheapness, which enables tis to furnish them to railroads in smaller 
quantities and at a lower price than they could be obtained by lithographic or any 
other process. 

The "Speed Protractor,'^ Avhich is generally used witli the Charts, needs hardly any 
recommendation. The simplicity of its construction, the care bestowed in its munuj'ac- 
ture, its greater accuracy tlian that of the semicircular angle protractor, and its low 
price, speak for themselves. 

The price of the Charts, without name of stations, station lines, and heading, is 
$12.00 per quire ; complete and ready for train plotting, the scale of prices is as fol- 
lows, viz. :

In favoring us with an order for complete Charts, please send list of stations with 
intermediate distances, and underscore such stations as you may desire to have printed 
in heavy type on account of their importance. 

The following is an extract from a letter of Mr. James Tillinghast, General Super- 
intendent of the New York Central and Hudson River Eailroad, to whose judgment 
Mr. Hill submitted both Charts and Protractor: 

" New York Central and Hudson River Railroad, 1 
Gen'l Supt. Office, Albany, N. Y., Jan. 15th, 1876. / 
" Albert Hill, Esq. : 

"Dear Sir: — I am in receipt of yours of the 14th inst., with sample of diagram of 
Chart sheets. -^ ^ -^ ] Jiave not found any better plan to secure accuracy in form- 
ing the basis or proof of time tables, for the reason that it presents to tiie eye in a clear, 
condensed form, all the trains the schedule is to cover, and in such manner that tiie 
station figures are accurately indicated, and from which tiie figures for the printed form 
can be readily copied. 

"Your plan o^ ^ Speed Protractor' is the best t have seen, and will be very useful in 
connection with the ('harts, and I have no d()ul)t that, with the facilities you meution 
for the production of charts so accurately lined as your process will produce, you will 
be able to secure orders. * * * 

" Yours truly, 

"James Tillinghast."
